如何在tablayout的底部显示AdMob广告

Question

我知道这个问题被问早前很多次，但所有这些工作对我的答案不是......

我有drawerlayout，tablayout和viewpager一个活动我想说明admob广告在viewpager的底部，这样当用户在viewpager上滑动时，广告会一直显示在底部。

这里是我的代码：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    xmlns:ads="http://schemas.android.com/apk/res-auto" 
    android:id="@+id/nav_drawer" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true" 
    tools:context=".MainActivity"> 

    <LinearLayout 
     android:id="@+id/appBarLinearLayout" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical"> 

     <android.support.design.widget.AppBarLayout 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> 

      <include 
       android:id="@+id/app_bar" 
       layout="@layout/app_bar" /> 

      <android.support.design.widget.TabLayout 
       android:id="@+id/tab_layout" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       app:tabTextColor="@color/lightPrimaryColor" 
       app:tabSelectedTextColor="@color/textIcons"/> 

     </android.support.design.widget.AppBarLayout> 

     <android.support.v4.view.ViewPager 
      android:id="@+id/viewpager" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      app:layout_behavior="@string/appbar_scrolling_view_behavior" /> 

     <FrameLayout 
      android:id="@+id/nav_contentframe" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:layout_marginTop="?attr/actionBarSize" 
      android:background="@android:color/background_light"/> 

    </LinearLayout> 

    <android.support.design.widget.NavigationView 
     android:id="@+id/nav_view" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_gravity="start" 
     android:fitsSystemWindows="true" 
     app:headerLayout="@layout/drawer_header" 
     app:menu="@menu/menu_drawerlist"/> 

</android.support.v4.widget.DrawerLayout> 

我尝试添加AdMob广告像下面这样viewpager和FrameLayout里：但是这并不在屏幕上显示的广告

<LinearLayout 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:gravity="bottom|center_horizontal" 
    android:orientation="vertical"> 

    <include 
     android:id="@+id/admob" 
     layout="@layout/admob" /> 
</LinearLayout> 

Answer 1

您应该使用Relative Layout并设置android:layout_alignParentBottomtrue

<RelativeLayout 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_alignParentBottom="true"> 

    <include 
     android:id="@+id/admob" 
     layout="@layout/admob" /> 
</RelativeLayout> 

安卓layout_alignParentBottom

如果为true，使得这一观点的底部边缘父的底部边缘相匹配。容纳底部边缘。
